[quote=afx114]It’s a bit complicated to call it just a currency or just a commodity. Mining is only one part of it (the commodity part). The other part is as a currency.

A currency is commonly used as a medium for exchange of goods or services. A commodity is something that is bought and sold with currency.
I believe bitcoin is currently a commodity because people hardly ever use bitcoins to pay for something. They buy bitcoins as a means to someday sell them at a higher value (in some currency such as $) in the future. They then then sell them and use a common currency (like euros or dollars) to buy stuff.
